                One of the most important purposes in local studing and land use evaluation the hazards of erosion in various areas and determing its quantity. For evaluating erosion , there are many metods . In this methods, there are different factors such as rain erosion , value of erosion soil and plant coverage . According to important variables that have influence on above factor and total value of erosion distiribution and geographical dispersion and the way of interfering them in change rate of soil erosion also determined. Although there are different methods e for evaluating erosion hazards, SLEMSA model. Because of using curvature correlation, serving effective factors in erosion, determining  value interfering factors based on their significance with a ratio of weight and finally considering all of effects in this model have optimal potential power. In this study, for evaluating soil erosion at basin watershed of Mousa Abad in Tiran by using SLEMSA modle, the first we begin to collect, prepare and enter information  layers such as topography, climatological, plant coverage and outer level of the land, then with composing this layers, basin is separated to410 units of sedimentation      that 220  are upward and 210 are in downward. At the end, the value of erosion hazard is measured and giving value is as unit of erosive hazard in basin (EHU).                                Manuscript profile
